There are two proposed scenarios for the connection between the western Laurentian rift system and the eastern system as manifested by segments of the rift system in Sonora, northern Mexico: (1) offset by the younger San Andreas fault system and Mojave-Sonora megashear (Stevens et al., ; Stewart, a, ), or (2) poorly preserved.

Paleozoic Era, also spelled Palaeozoic, major interval of geologic time that began million years ago with the Cambrian explosion, an extraordinary diversification of marine animals, and ended about million years ago with the end-Permian extinction, the greatest extinction event in Earth history.
The major divisions of the Paleozoic Era, from oldest to youngest, are the Cambrian ( Notably, the division of the Hayfork into the eastern and western Hayfork terranes by Wright () and the definition of the Sawyers Bar composite terrane, combining the North Fork and eastern Hayfork lithotectonic entities (Ernst,; Hacker et al., ), have contributed to the current divisions of the western Paleozoic and Triassic.

During the Late Paleozoic, the Gondwana supercontinent plausibly reached its maximum expansion, encompassing Australia, India, Antarctica, part of South Africa, the southern half of South America, and a poorly defined group of perigondwanic basins (for a review, see Veevers and Powell, ).The western margin of Gondwana, represented in the vast Upper Paleozoic.

Blodgett, George D. Stanley, Jr. The Paleozoic is bracketed by two of the most important events in the history of animal life. At its beginning, multicelled animals underwent a dramatic "explosion" in diversity, and almost all living animal phyla appeared within a few millions of years.
